An Online the perception of creating a small made popular table-top High definition tv antenna is known as a "coat-hanger" or "cat-whisker" type. The main one referred to in the following paragraphs is patterned after it, even though it is modified and bigger,

Rather than using coat-wardrobe hangers or costly solid copper wire to really make it, this bigger one uses cheap one-inch strips of thin sheet-aluminum rather. These strips will pickup TV signals well. In the end, most TV antennas are constructed with aluminum.

Parts (from discount hardware/electronics stores)

Wood board: one 1x3-inch x 6-ft () scrap is effective.Step-flashing sections or equivalent: seven 8x8-inches, hin aluminum ($.60 each)Solid aluminum wire or similar: two 6-ft measures, 12-14-gage ()Screws: 26 of size 8x3/4-inch, wide-mind ()Washing machines: 26 of size 1/2-inch-OD (.50)Balun: one easy male cable connector getting two stretching wires with spade tips (.50)Reflectors: two bits of heavy card board, 2x3-ft each, getting one for reds engrossed in aluminum foil folded around their edges (). Note: light metal cage or wire-mesh also works best for reflectors.Staples or screws: small ones for affixing the reflectors towards the back side from the antenna board.Coaxial TV cable: enough for connecting the antenna towards the TV(s) -25

This antenna is split into two identical parts whose combined receptions are introduced towards the balun. Each half appears like a row of miniature rabbit-ears (V's) connected to the rims from the board.

1. Around the flat side from the board, convey a pencil mark 2-inches from each finish from it. Between both of these marks, make 11 more marks evenly spread to provide as many as 13 evenly spread ones about 5.7-inches apart.

2. At these marks 5/8-inches in the lower and upper rims from the board, drill 3/16-inch screw holes. This method makes two 13-hole rows across the lower and upper rims from the flat side.

3. Using the scissors, cut each aluminum expensive panel into eight 1-inch-wide strips for as many as 56 strips 8-inches lengthy. 52 of these will enter in the antenna four are spares.

4. With two strips, form V-shape by overlapping the low tips. Drill singleOr4-inch hole through the middle of the overlap.

5. Having a screw & washer, attach the V-overlap towards the board at among the drill holes, although not stiffened completely lower. Towards the top of the V, allow a middle-to-center three-inch gap as proven in reference-1 below.

7. In the screw sites of every row of V's, place one 6-feet entire solid wire beneath these overlapping strips, after which tighten the screws/washing machines lower tightly upon it while keeping a 3-inch gap towards the top of the V's.

8. If required, reshape the strips so that they are fairly straight.

9. Slightly release the 2 screws from the middle set (of every row), and fix one spade from the balun to them tightly.

11. Within the loft, mount the antenna up and down or flat as space enables, the V-rows facing the broadcasting stations searched for.

12. Attach the cable towards the antenna, and run it towards the TV.

Discussion

This reflector-backed antenna can be created bigger or more compact compared to one referred to because needed. It'll get the majority of the UHF channels well (individuals above funnel-13), based on their individual broadcasting talents.

Also, for more powerful all-around reception still, it may be linked to a mature traditional VHF aluminum antenna that may be set up in the loft from years past (for channels-13 and below). For additional info on this homemade antenna design, see these web sites.
